Ranger Posted April 27, 2004 Report Share Posted April 27, 2004 If the FPR is not leaking gas from the vacuum line with the engine running, then it's good. Have you checked/cleaned the EGR valve? Link to comment Share on other sites More sharing options...
btk03 Posted April 27, 2004 Report Share Posted April 27, 2004 A good sign that the FPR is no good is after the car has been sitting, you go to start it, and it cranks longer than normal. Once it is started and you turn it off, and then try starting again, it will start right up. It is only after the car has been sitting for a period of time that I noticed the FPR was bad. It never showed any signs of leakage. Just pop the original one out, and put the new one on and you will be on your way. I hope this helps. Bill....

Be sure when you clean it not to allow the solvent (carb cleaner) to run down into the can. It will destroy it. Hold it up right so the solvent runs down toward the pintle. Soot on it is ok, as long as the pintle moves freely and doesn't stick. Caked carbon should be cleaned off. Pintle should be spring loaded in the closed position. If it sticks open that may be your problem. Link to comment Share on other sites More sharing options...
